WAVE-MOTO R.

SPEOIFIGATIONforming part off Letters Patent No. 735,510, dated August 4, 1903.

A iimion fil d October 21.19o2. Serial No. 128,106. (Nomod'eL) To all whom, it may concern:

Be it known that we, JOHN CHRISTOPHER Bronx, in the countyand State of New York,

have invented a new and useful Improvement in Wave-Motors, of which the following is a full, clear, and exact description.

useful improvements in the construction of an apparatus designed to utilize the motion.

imparted by waves.

provide a mechanism which may be readily assembled upon a hull or float of the desired character and which shall be so constructed that it shall be positive in its operation and simple in construction.

To this end the invention consists in the "peculiar construction, combination, and arrangement of parts, as will be hereinafter fully described in the specification, illustrated in the accompanying drawings, and pointed out in the appended claims.

While we have herein shown and described our preferred form of apparatus, it will of course be understood that there can be changes and modifications madelthe'rein in several respects without departing from the spirit of the invention or sacrificing any of the advantages thereof.

Reference is to be hadto the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a vertical sectional view in side elevation, showing our improved apparatus.

Fig. 2 is a top plan view of the same, showing the manner of arranging the cables or ropes passing over the sides and ends of the float and encircling the winding-drums; and Fig. 3 is a side View of the pawl-and-ratchet mechanism for actuating the gear-wheels which engage'with the pinion-wheel mounted on the shaft journaled in the main frame.

Referring now to the drawings in detail and in particular .to Fig. 1 thereof, the numeral l designates a float or hull of any desired form or character, adapted to float on the surface of a body of water. On this float,

ranged transversely or at rightangles.

preferably in the central portion thereof, is mounted a framework 2, which for the sake of convenience we may hereinafter designate as a main frame. Journaled in this main frame, as at 3 and 4, are two horizontally-disposed shafts, having mounted thereon so that they may freely rotate the drums 5, 6, 7, and 8. These drums may for the sake of con- I venience be arranged as more clearlyshown This invention relates to'certain novel and g in Fig. 2that is, the drums 5, 6, 7, and 8 may be arranged, respectively, side by side. Mounted on the shafts 4 and 5, between the above-referred-to drums, are the gear- The object of the present invention is towheels 9 10, adapted to engage or mesh with the pinion-wheel 11, carried by the horizontally-disposed shaft 12, which is mounted in the aforesaid main frame intermediate the winding-drum shafts. Aspring-tension pawl, as at 13, is pivoted on either side of the aforesaid gear-wheels 9 10, said pawl being adapted to engage with the ratchet-Wheels 14c 14, secured to the inner ends of the windingdrums. By this arrangement it will be seen that when the drums are rotated through any means the gear-wheels 9 and 10 will also be caused to rotate through the pawl-andratchet connection and will in turn cause the revolution of the pinion-wheel 11 and the shaft 12. At the outerend of the shaft 12, as at 14*, may be mounted a pulley or wheel for utilizing the motionrfor any desired purpose.

Suspended beneath the aforesaid float 1, at a point substantially central thereof, and thus directly beneath the frame 2, is a vane or rudder 15. This vane may be formed of any suitable weighty materiala'nd is constructed, preferably, as shown, of wings arcured to the lower end of one of the aforesaid wings, asat 16, is the end portion of a cable'17; said cable extending upwardly and passing around a pulley 18, mounted at one end of the aforesaid float. This cable extends across the float, encircling the drums 6 and.8, and is secured at its other end to the opposite sideof the vane, asat 19.- A second rope orcable, as at 20, is similarly mounted at right angles to the first-mentioned .cablethat is, it is attached to the other wings of the vane, which wings are at right angles to the first-mentioned wings supporting the cable 17-and the last-mentioned cablepasses over a guide-pulley 21, encircles the drum 5 and 7, and is secured in a manner similar to the first-described cable.

Attached to the cables 17 and 20, as clearly shown in Figs. 1 and 2 at 21, are the ropes 22 and 23, supporting at their lower ends the cone-shaped weights 24. While these weights may be of any suit-able character, we prefer ably make them in the form of a hollow cone, as we have found such will sink very easily, but will ofier considerable resistance on being pulled upward toward the surface of the Water.

From the above description, taken in connection with the accompanying drawings, the operation of our improved apparatus will be readily understood. As the hull or float 1 is tilted or changes its position through the action of the waves, the vane 15, being composed of a very heavy material, will retain its stationary position and the action of the waves will cause the drums to rotate, and through the action of the pawl-and-ratchet mechanism and the gear-wheels, as above described, the pinion on the shaft 12 will also rotate, causing the revolution of the aforesaid shaft.

For the purpose of holding or retaining the float and its parts in any desired position or locality any suitable or preferred form of anchor or anchoring means (not shown) may be employed. If near or adjacent to shore, it may be moored to a suitable support, or if some distance out from land an anchor suitable to the nature of the bottom over which the float rides may be used.

Having thus described our invention, we claim as new and desire to secure by Letters Patent- 1. In an apparatus of the class described, the combination of a float, a frame mounted thereon, a vane suspended beneath said float, drums mounted on shafts journaled in said frame, a shaft carrying a pinion mounted on the frame intermediate the drum-carrying shafts, the aforesaid pinion meshing with gear-wheels rotated through the movement of the winding-drums, and cables passing over said drums and having their end portions secured to the aforesaid vane, the construction being such that as the float is tilted through the movement of the waves the cabios and their attached parts cause the winding-drums to rotate, operating the pinion and its shaft through the aforesaid gear-wheel.

2. In an apparatus of the class described, the combination of a float, a frame mounted thereon, a vane suspended beneath said float, Winding-drums revolubly mounted on the shafts journaled in said frame, a shaft also mounted in said frame intermediate the drum-carrying shafts, a pinion-wheel mounted on said second shaft and meshing with gear-wheels rotated by the movement of the aforesaid drums, and means connected with the aforesaid vane for rotating said drums when the float is tilted through the action of the waves.

3. In an apparatus of the class described, the combination of a float, a frame mounted thereon, a vane suspended beneath the float, horizontally-disposed parallel shafts spaced apart and journaled in said frame, windingdrums mounted on said shafts, a pinionwheel carried by a counter-shaft mounted in the frame between the drum-carrying shafts, gear-wheels meshing with the aforesaid pinion-wheel, for rotating the latter when actuated by the revolution of the drums, cables passing around said drums and secured to the aforesaid vane, and weights suspended from said cables.

4. The combination of a float, a frame mounted thereon, a vane suspended beneath said float, shafts journaled in said frame, drums mounted in pairs on said shafts, a pinion -wheel and shaft mounted intermediate said drum-carrying shafts, gear-wheels on each of said drum-carrying shafts, connected with said drums by pawl-and-ratchet devices and meshing with the aforesaid pinions, pulleys on said float, cables bearing on said pulleys and extending across said float transversely of each other and encircling parallel drums of opposite pairs, said cables being connected at their ends to the vane, and weights secured to said cables, substantially as described.

In testimony whereof we have signed our names to this specification in the presence of two subscribing witnesses.
